Abstract
OBJECTIVES: To evaluate the effects of an exercise intervention on physical function, maximal muscle strength, and muscle power in very old hospitalized patients.
DESIGN: In a randomized controlled trial, 130 hospitalized patients were allocated to an exercise intervention (n = 65) or a control group (n = 65). The intervention consisted of a multicomponent exercise training program performed during 5-7 consecutive days (2 sessions/d). The usual care group received habitual hospital care, which included physical rehabilitation when needed.
SETTING AND PARTICIPANTS: Acute care for elderly unit. Older adults age >75 years.
MEASURES: Physical function, assessed with the Short Physical Performance Battery test and the Gait Velocity Test (GVT), were the primary endpoints. The GVT was also administered under dual-task conditions (ie, verbal and arithmetic GVT). The functional tasks were recorded using an inertial sensor unit to determine the movement pattern. The secondary endpoints were maximal muscle strength and muscle power output.
RESULTS: The exercise intervention program provided significant benefits over usual care. At discharge (primary time point), the exercise group showed a mean increase of 1.7 points in the Short Physical Performance Battery scale (95% confidence interval [CI] 0.98, 2.42) and 0.14 m·s-1 in the GVT (95% CI 0.086, 0.194) over the usual care group. The intervention also improved the verbal (0.151; 95% CI 0.119, 0.184 vs -0.001; 95% CI -0.025, 0.033 in the control group) and arithmetic GVT (0.115; 95% CI 0.077, 0.153 vs -0.004; 95% CI -0.044, 0.035). Significant benefits were also observed in the intervention group in movement pattern, as well as in muscle strength and muscle power.
CONCLUSIONS AND IMPLICATIONS: An individualized multicomponent exercise training program improves physical function, maximal muscle strength, and muscle power in acutely hospitalized older patients. These findings support the importance of physical exercise for avoiding the loss of physical functional capacity that frequently occurs during hospitalization in older adults.
